The British Pound is formally referred to as "pound sterling." It was originally used in Anglo-Saxon England and was equivalent to one pound in weight of silver. The pound is divided into a hundred pence, similar to the U.S. dollar, which is divided into a hundred pennies. The front of the coin features the profile of Queen Elizabeth II since the coin's latest redesign in 1990.
